My review is a bit late in coming, but that's not because the accommodations were inadequate. I stayed for a month and had a great time.
The condo is a bit far out from the city in a quieter, residential area. However, the BTS right outside, so you can be shopping in central Bangkok in 30 minutes. Amenities around the building include a 7/11, some smaller restaurants and street vendors.
The apartment itself was wonderful. It's small, so best for a single traveler or a couple. However, its a modern place in a newer building. The bed is comfy and the shower is great. There's a gym and pool on site, too, as well as a small library to work in.
Overall, I really liked this place and felt like it was worth the cost. I would definitely stay here again. I would recommend it for business travelers or mature individuals that aren't looking for the loud Khao San Road experience, and who just want to get a nice feel for a local community while having easy access to the city.
